Greece are supposed to be in the EU, and with all the european lark they should act accordingly, Yes these guys were wrong, but I think within the EU it should have been a ticking off etc etc, go home.
Now what I cannot understand is how Greece is so convinced that there technology is so advanced that it has to be protected, very strange. I get the impression they are becoming similar to the african 3rd world countries who are convinced that because they have 2 guns and a helicopter they can take on the world, they then argue that because a british person has seen the weapons that he is spying, and don't understand when you explain that you can buy the same stuff in europe 'fairly easily', its a very strange scenario.
